Answer:

The top left graph is the correct one.

Step-by-step explanation:

The graph of y = 1/2x - 4 will rise to the right , have a slope of 1/2 and pass through the point (0, -4) on the y-axis.

Since the inequality sign is 'less than or equal to' the line will be continuous and the shading will be below this line.

5x-3y=1,3x+2y=1 solve the simultaneous equation above

ryzh [129]

Answer:

The solution to the equation is as follows;

$x = \frac{5}{19} ,\ and \ y= \frac{2}{19}$

Step-by-step explanation:

Given;

5x - 3y = 1

3x + 2y = 1

Solving both equation simultaneously;

2: 10x - 6y = 2

3: 9x + 6y = 3

--------------------------

19x + 0 = 5

x = 5/19

substitute the value of x in any of the equations above and solve for y;

5x - 3y = 1

5 (5/19) - 3y = 1

25/19 -3y = 1

$3y = \frac{25}{19} -1\\\\3y = \frac{25-19}{19} \\\\3y = \frac{6}{19} \\\\y = \frac{2}{19}$

The length of a rectangle is one foot more than twice its width. If the area of the rectangle is 300ft2, find the dimensions of

Gemiola [76]

Answer:

12 ft x 25 ft

Step-by-step explanation:

If L is the length and W is the width:

L = 2W + 1

300 = LW

Substitute:

300 = (2W + 1) W

300 = 2W² + W

0 = 2W² + W − 300

0 = (2W + 25) (W − 12)

W = 12

L = 2W + 1

L = 25

The rectangle is 12 feet wide and 25 feet long.

Solve the following proportion n/6=15/3

Natalka [10]

We can simplify 15/3 to 5.

N/6 = 5. Then multiply both sides of the equation by 6, giving us N = 30.
